Any other possitive factors  - stable tenant base  - alarm systems  - regular checks on the property  - no pets  - Lead safe certification  - newer roof, plumbing, electric, etc..Anything to balance off the lossesBe prepared that it may end up in a non-standard (surplus lines) market for a couple of years.If you did not have flood coverage before, see if they will continue the current policy if you get Flood coverage and increase the property coverage deductible. 

Personally, if the pipe fittings were not leaking, and did not show signs of significant corrosion, then I would probably leave them alone until there was an issue.

The roofs were updated in 2021.All units are currently occupied on month-to-month leases, with three tenants paying $1,425 per month and one tenant paying $1,300 for handling lawn care and maintenance.

Plumbing, roofs, HVAC, hardscape are expensive.  

Hi there, I am running a business with property management, construction and investor focused agents all working under one roof.

Roofs are $10-15,000 for a typical duplex where I live.  

3. requiring heavy amount of rehab (siding, foundation, roof, HVAC, appliances)?

If they find the tank has leaked the costs go up big time .

Roofs and 'lesser' critical home hardware like HVAC, AC, plumbing and non functioning lighting and electrical.
